You can still drive on with the condition; however, you should not, for a long time. The heater core uses the engine’s coolant, and a faulty heater core affects the cooling effect which then raises the temperature. Not curing the issue and continue to drive the vehicle this way can lead to further engine damage.Click to see full answer. Consequently, what happens when a heater core goes bad?A heater core often goes bad due to leaking. As the heater core uses engine coolant to generate heat, a leaking heater core will reduce the amount of coolant in the cooling system. Low coolant will cause an engine to run at a higher temperature, which can result in extensive engine damage.Subsequently, question is, will heater core leak if heat is off? Hot coolant won’t flow through it when the heater knob is off, but coolant will still sit in the heater core, and can still leak regardless. Subsequently, one may also ask, how much does it cost to replace a heater core? Replacing the heater core can be an expensive job, and usually costs between $564 – $927 for parts and labor. The parts aren’t particularly expensive, normally costing $80 – $234, but the location of the heater core means that labor costs tend to be quite high.Does heater core affect AC?The heater core will not cause the A/C to not blow cold. If your A/C is working properly with the correct amount of refrigerant, then you may have a temperature blend door not working and staying on heat mode.
